Hi Dealspeed.

Check this link to another thread here on RCU. About half way down the page you'll see a post with four pics of an engine that has been sealed up.

I highly recommend Lucky 7. It's what a number of engine modders use...and that's good enough for me not to bother screwing around with anything else.
